Description
This function transmits a
number of bytes synchronously to the receiver,
and waits for the receiver to reply. There is
no limit to how long the receiver may delay
prior to replying. The reply data will be written into
inbuf, up to lin bytes.
If the inbuf data area is not large enough to
accommodate the entire reply, then the result is OS-dependent. This
will change in future versions of this API.
